I am adding record in grid using startEditingNew method as below.
var COLUMN_NAME = {
name : "user_name",
lastname : "user_surname",
age : "user_age"
};
addDataToGrid : function (name, lastname, age){
MyGrid_Grid.startEditingNew({
COLUMN_NAME.name: name,
COLUMN_NAME.lastname: lastname,
COLUMN_NAME.age: age
});
}
But, my above function raise error and does not add record to grid.
If I use "user_name" string instead of "COLUMN_NAME.name" , It works fine.
How can I use variable as column name??
Thanks in advance
This is a javascript question, not a SmartClient one.
Anyway, if you need to use that approach, you may write something like:
addDataToGrid : function (name, lastname, age){
var record = {};
record[COLUMN_NAME.name] = name;
record[COLUMN_NAME.lastname] = lastname;
record[COLUMN_NAME.age] = age;
MyGrid_Grid.startEditingNew(record);
}

I have a Angular5 based front-end which needs to show a list of persons. A similar list is shown at the back-end application. Both lists need to be sorted exactly the same. The back-end list is fetched via a query in MSSQL DB which uses an 'order by' clause like this :
select * from PERSON where GROUP=1 order by PERSON.LAST_NAME ASC, PERSON.INITIALS ASC, PERSON.PREFIX ASC, PERSON.FIRSTNAME ASC
On the frontend, my person model looks like :
export interface Person {
id?: number;
fullName?: string;
}
The fullName here is as per this format : [LastName, Initials Prefix FirstName] eg : Adams, Mr P John.
I am using this method to sort it :
public sortByName(aPersonArr: Person[]) {
aPersonArr.sort((p1, p2) => {
let name1 = p1.fullName;
let name2 = p2.fullName;
// If both names are blank, consider them equal, If one name is blank, place it at the last
if (!name1 && !name2) {
return 0;
} else if (name1 && !name2) {
return -1;
} else if (name2 && !name1) {
return 1;
}
name1 = name1.toLowerCase();
name2 = name2.toLowerCase();
if (name1 < name2) {
return -1;
}
if (name1 > name2) {
return 1;
}
return 0;
});
}
}
But the problem occurs when a person's fullName begins with a special character because SQL Query fetches the names in this order : (Showing only the lastNames here)
*Account
,Adams
.Alkin
+Account
-Adams
Whereas my typescript code sorts them like this : (Showing only the lastNames here)
*Account
+Account
,Adams
-Adams
.Alkin
The reason that I need to have this logic at frontend is that many a times my person list is dynamically prepared and needs to be sorted right away. Is there a way to know what exact logic is used by SQL query to compare strings, so that i can use the same in my sorting method.
In Groovy to set a bean you just need to give the GroovyRowResult while creating object.
Consider below People.groovy bean:
class People {
String name
int age
}
My sql query:
select * from People -- returns name and age of people
the GroovyRowResult is returned with column names (keys) in capitals like it:[NAME:"Alex", AGE: 21].
So when I try to set the bean like below:
le.rows(sqlQuery).each {
People p = new People(it)
}
I receive the Exception:
groovy.lang.MissingPropertyException: No such property: NAME for class: People. Possible solutions: name
I guess I can modify sql query to include double quotes on the alias, but have you guys handled it any different?
The rows() method returns a List<GroovyRowResult> where GroovyRowResult implements Map and then you can apply collectEntries to transform it, so that the keys are lowercase and you can use the resulting map:
sql.rows('select * from people').each {
People p = new People(it.collectEntries { k,v -> [k.toLowerCase(), v] })
println p.name
println p.age
}
In my grails project I create instances of an object called Patient, that has got a field city.
class Patient {
String name;
String surname;
String cf;
String address;
String cap;
String city;
String province;
String country;
String phone_1;
String phone_2;
String email;
String vat;
}
When I create a Patient, I store city by its id, but I want that, in show() and list() methods, I see the name of the related city.
The Cities domain class is linked to a table in my db as follows
class Cities {
String cityName;
String capOfCity;
String provinceOfCity;
static constraints = {
}
static mapping = {
table 's_cap'
id column: 'idcap'
cityName column: 'comune'
capOfCity column: 'cap'
provinceOfCity column: 'prov'
version false
}
}
I suppose that I must perform a query to db to get its name by id, but how can I do it in gsp?
With your current approach you can do
def show(){
// look up your patient object
def patient = Patient.get(123)
def patientCityObject = Cities.findByCityName(patient.city)
[patientCityObject: patientCityObject ]
}
GSP:
<p>${patientCityObject.cityName}</p>
However,
If you define the association between your domains then Grails will load your city when you are accessing it. To access you city object associated with Patient, you can define it as follow:
class Patient {
...
Cities city;
...
}
Then when you have the patient object, you can easily access its property city.
def patient = Patient.get(123)
patient.city.cityName
This will give you the city object associated with your patient. Then you can pass that into your GSP and use it.

Really stuck with Linq to SQL grouping and summing, have searched everywhere but I don't understand enough to apply other solutions to my own.
I have a view in my database called view_ProjectTimeSummary, this has the following fields:
string_UserDescription
string_ProjectDescription
datetime_Date
double_Hours
I have a method which accepts a to and from date parameter and first creates this List<>:
List<view_UserTimeSummary> view_UserTimeSummaryToReturn =
(from linqtable_UserTimeSummaryView
in datacontext_UserTimeSummary.GetTable<view_UserTimeSummary>()
where linqtable_UserTimeSummaryView.datetime_Week <= datetime_To
&& linqtable_UserTimeSummaryView.datetime_Week >= datetime_From
select linqtable_UserTimeSummaryView).ToList<view_UserTimeSummary>();
Before returning the List (to be used as a datasource for a datagridview) I filter the string_UserDescription field using a parameter of the same name:
if (string_UserDescription != "")
{
view_UserTimeSummaryToReturn =
(from c in view_UserTimeSummaryToReturn
where c.string_UserDescription == string_UserDescription
select c).ToList<view_UserTimeSummary>();
}
return view_UserTimeSummaryToReturn;
How do I manipulate the resulting List<> to show the sum of the field double_Hours for that user and project between the to and from date parameters (and not separate entries for each date)?
e.g. a List<> with the following fields:
string_UserDescription
string_ProjectDescription
double_SumOfHoursBetweenToAndFromDate
Am I right that this would mean I would have to return a different type of List<> (since it has less fields than the view_UserTimeSummary)?
I have read that to get the sum it's something like 'group / by / into b' but don't understand how this syntax works from looking at other solutions... Can someone please help me?
Thanks
Steve
Start out by defining a class to hold the result:
public class GroupedRow
{
public string UserDescription {get;set;}
public string ProjectDescription {get;set;}
public double SumOfHoursBetweenToAndFromDate {get;set;}
}
Since you've already applied filtering, the only thing left to do is group.
List<GroupedRow> result =
(
from row in source
group row by new { row.UserDescription, row.ProjectDescription } into g
select new GroupedRow()
{
UserDescription = g.Key.UserDescription,
ProjectDescription = g.Key.ProjectDescription,
SumOfHoursBetweenToAndFromDate = g.Sum(x => x.Hours)
}
).ToList();
(or the other syntax)
List<GroupedRow> result = source
.GroupBy(row => new {row.UserDescription, row.ProjectDescription })
.Select(g => new GroupedRow()
{
UserDescription = g.Key.UserDescription,
ProjectDescription = g.Key.ProjectDescription,
SumOfHoursBetweenToAndFromDate = g.Sum(x => x.Hours)
})
.ToList();
In my VB.NET code, I have something like this:
A collection of clsEmployees, which is made up of clsEmployee objects.
I would need a LINQ statement, such that it would return me a DataTable, made up of rows of fields of clsEmployee, which are supposedly firstname, lastname, employeeID, phone, city etc.
Also, the LINQ statement should return only those rows where phone is not null.
Something like
var aList = empList
.Where((e) => e.phone != null)
.Select((e) => new { firstname : e.firstname, lastname : e.lastname }); // etc
If you really need rows you can use new DataRow(...) in the select.
